Beitr. 47/1 207-248 31.7.2015 On the Nepalota fauna of China (Coleoptera: Staphylinidae: Aleocharinae: Athetini) Volker ASSING A b s t r a c t : Types and additonal material of the East Palaearctic aleocharine genus Nepalota PACE, 1987 are examined. Eleven species are (re-)described and illustrated: N. franzi PACE, 1987; N. globifera PACE, 1998; N. smetanai PACE, 1998; N. guangdongensis PACE, 2004; N. fellowesi PACE, 2004; N. crocea nov.sp. (Yunnan); N. cuneata nov.sp. (Yunnan); N. mocytoides nov.sp. (East Yunnan); N. prominula nov.sp. (Yunnan); N. tuberifera nov.sp. (Yunnan); N. daweiana nov.sp. (Yunnan). Five synonymies are proposed: N. gansuensis PACE, 1998 = N. qinlingmontis PACE, 2011, nov.syn.; N. globifera PACE, 1998 = N. caluoensis PACE, 2011, nov.syn., = N. daxuensis PACE, 2011, nov.syn.; N. guangdongensis PACE, 2004 = N. rougemonti PACE, 2011, nov.syn. = N. ruficollis PACE, 2011, nov.syn. Nepalota franzi is reported from China for the first time. In all, 35 valid species are currently known from the East Palaearctic, four of them of doubtful status (males unknown). Twenty species have been described or reliably recorded from China exclusive of Taiwan. The diversity is greatest in Yunnan (fourteen species, seven of them exclusive), followed by Hubei (five species; three exclusive); Sichuan (four species, one exclusive), Gansu and Shaanxi (three species each), Guangdong (two species), Zhejiang, Chongqing, Jiangxi, Guangxi, Guizhou, and Beijing (one species each). The distributions of 15 species are mapped. An updated checklist of Nepalota is provided. K e y w o r d s : Coleoptera, Staphylinidae, Aleocharinae, Athetini, Nepalota, East Palaearctic region, China, taxonomy, new species, new synonymies, new records, checklist. Introduction The athetine genus Nepalota PACE, 1987 is distributed in the southern East Palaearctic region sensu SMETANA (2004) and the northern Oriental region, from Kashmir across the Himalaya, Burma, and China to Japan and North Korea. It was previously represented by 34 named species. As many as seventeen species have been recorded exclusively from China, four exclusively from the Himalaya, two from both China and Nepal (one of them also from Burma), five from Taiwan, five from Japan, and one from North Korea (ASSING 2003; PACE 2004, 2009, 2011; SMETANA 2004). In China, the provinces with the greatest diversity were Sichuan (seven species) and Yunnan (six species), followed by Hubei (five species), Shaanxi (three), Gansu (two), Guangdong (two), and Guangxi (two species). Only one species each had been reported from Guizhou, Zhejiang, Beijing, and Gansu. © Biologiezentrum Linz, download www.zobodat.at 208 Nepalota species are characterized by a mostly relatively robust habitus similar to that of some groups of Atheta THOMSON, 1858 and Liogluta THOMSON, 1858, by a usually slender median lobe of the aedeagus with a more or less deeply bifid ventral process, and by a relatively uniform spermatheca with a rather long, curved, and proximally twisted proximal portion of the capsule. In addition, Nepalota species often display a more or less pronounced sexual dimorphism of the pronotum, of the anterior and posterior abdominal tergites, and of sternite VIII (ASSING 2003). The most reliable characters for an identification at the species level are the male primary and secondary sexual charac- ters. The spermatheca, on the other hand, is often of rather uniform shape, particularly so among closely related species, and subject to more or less pronounced intraspecific variation, and consequently of little use for taxonomic purposes. Nevertheless, as many as eight species have been described based exclusively on females (PACE 1986, 1991, 1998, 2004, 2009, 2011). Moreover, several subsequent records of these and other species are based on females only and thus unreliable. For an overview of doubtful species and records see the catalogue at the end of this article. The present contribution focuses on Nepalota material collected during two field trips to China conducted in 2012 and 2014, as well as on additional material from the collection of Michael Schülke (Berlin). Moreover, the types of several species were examined. In order to facilitate future taxonomic and faunistic work on the Nepalota fauna of China, literature data are considered and an updated catalogue is provided. Material and methods The material treated in this study is deposited in the following collections: IRSNB..............Institut Royal des Sciences Naturelles de Belgique (Y. Gérard) MHNG .............Muséum d'Histoire Naturelle, Genève (G. Cuccodoro) MNHUB...........Museum für Naturkunde der Humboldt-Universität Berlin (J. Frisch) NMP.................National Museum of Natural History, Praha (J. Hájek) SMF .................Senckenberg-Museum Frankfurt (A. Hastenpflug-Vesmanis) cAss..................author´s private collection cPüt ..................private collection Andreas Pütz, Eisenhüttenstadt cSch..................private collection Michael Schülke, Berlin The morphological studies were conducted using a Stemi SV 11 microscope (Zeiss Ger- many) and a Jenalab compound microscope (Carl Zeiss Jena). The images of the antennae, some of the forebodies, and the anterior portions of the male abdomina were created using a photographing device constructed by Arved Lompe (Nienburg) and CombineZ software. A digital camera (Nikon Coolpix 995) was used for the remaining photographs. The maps were created using MapCreator 2.0 (primap) software. Body length was measured from the labrum to the apex of the abdomen, the length of the forebody from the labrum to the posterior margin of the elytra, head length from the anterior margin of the clypeus (without ante-clypeus) to the posterior carina of the head, the length of the elytra along the suture from the apex of the scutellum to the posterior margin of the elytra, the length of the median lobe of the aedeagus from the apex of the ventral process to the base of the aedeagal capsule, and the length of the spermatheca is © Biologiezentrum Linz, download www.zobodat.at 209 given as the maximal extension (measured from the apex of the distal portion of the capsule) . The "parameral" side of the median lobe of the aedeagus (i.e., the side where the sperm duct enters) is referred to as the ventral, the opposite side as the dorsal aspect. The Nepalota fauna of China Including the new species described below and considering five new synonymies, Nepalota is currently represented in China exclusive of Taiwan by twenty valid species, one of them of doubtful identity. The diversity is greatest in Yunnan (fourteen species, seven of them exclusive), followed by Hubei (five species, three exclusive), Sichuan (four species, one exclusive), Gansu and Shaanxi (three species each), Guangdong (two species), Zhejiang, Chongqing, Jiangxi, Guangxi, Guizhou (one species each), and Beijing (one doubtful species). Disregarding the doubtful N. pernitida, only two species, N. martensi and N. franzi, are not exclusive to China, their vast distributions ranging from Nepal to southern Yunnan and Gansu. The remaining species have been recorded solely from China. While some of them are rather common and widespread, several species are known only from their respective type localities or their immediate vicinity. Based on personal observations and on the material examined, Nepalota species usually inhabit the leaf litter layer of various montane forest and shrub habitats. The altitudes range from 1200 to 3800 m. Nepalota dabamontis PACE, 2011 Nepalota dabamontis PACE, 2011: 173.

    Bulletin of the Irish Biogeographical Society Number 41 (2017) ADDITIONS, DELETIONS AND CORRECTIONS TO THE STAPHYLINIDAE IN THE IRISH COLEOPTERA ANNOTATED LIST, WITH A REVISED CHECK-LIST OF IRISH SPECIES Jervis A. Good1 and Roy Anderson2 1Glinny, Riverstick, Co. Cork, Republic of Ireland. e-mail: <[email protected]> 21 Belvoirview Park, Belfast BT8 7BL, Northern Ireland. e-mail: <[email protected]> Abstract Since the 1997 Irish Coleoptera – a revised and annotated list, 59 species of Staphylinidae have been added to the Irish list, 11 species confirmed, a number have been deleted or require to be deleted, and the status of some species and names require correction. Notes are provided on the deletion, correction or status of 63 species, and a revised check-list of 710 species is provided with a generic index. Species listed, or not listed, as Irish in the Catalogue of Palaearctic Coleoptera (2nd edition), in comparison with this list, are discussed. The Irish status of Gabrius sexualis Smetana, 1954 is questioned, although it is retained on the list awaiting further investgation. Key words: Staphylinidae, check-list, Irish Coleoptera, Gabrius sexualis. Introduction The Staphylinidae (rove-beetles) comprise the largest family of beetles in Ireland (with 621 species originally recorded by Anderson, Nash and O’Connor (1997)) and in the world (with 55,440 species cited by Grebennikov and Newton (2009)). Since the publication in 1997 of Irish Coleoptera - a revised and annotated list by Anderson, Nash and O’Connor, there have been a large number of additions (59 species), confirmation of the presence of several species based on doubtful old records, a number of deletions and corrections, and significant nomenclatural and taxonomic changes to the list of Irish Staphylinidae.

Based on an examination of type and non-type material, ten species-group names are synonymised: Atheta mediterranea G. Benick, 1941, Aloconota carpathica Jeannel et Jarrige, 1949 and Atheta carpatensis Tichomirova, 1973 with Aloconota mihoki (Bernhauer, 1913); Amischa jugorum Scheerpeltz, 1956 with Amischa analis (Gravenhorst, 1802); Amischa strupii Scheerpeltz, 1967 with Amischa bifoveolata (Mannerheim, 1830); Atheta tricholomatobia V. B. Semenov, 2002 with Atheta boehmei Linke, 1934; Atheta palatina G. Benick, 1974 and Atheta palatina G. Benick, 1975 with Atheta dilaticornis (Kraatz, 1856); Atheta degenerata G. Benick, 1974 and Atheta degenerata G. Benick, 1975 with Atheta testaceipes (Heer, 1839). A new name, Atheta velebitica nom. nov. is proposed for Atheta serotina Ádám, 2008, a junior primary homonym of Atheta serotina Blackwelder, 1944. A revised key for the Central European species of the Aloconota sulcifrons group is provided. Comments on the separation of the males of Amischa bifoveolata and A. analis are given. A key for the identification of Amischa species occurring in Hungary and its close surroundings is presented. Remarks are presented about the relationships of Alevonota Thomson, 1858 and Enalodroma Thomson, 1859. The taxonomic status of Oxypodera Bernhauer, 1915 and Mycetota Ádám, 1987 is discussed. The specific status of Pella hampei (Kraatz, 1862) is debated. Remarks are presented about the relationships of Alevonota Thomson, 1858, as well as Mycetota Ádám, 1987, Oxypodera Bernhauer, 1915 and Rhopaletes Cameron, 1939.

  • On Some Athetini from Armenia and Adjacent Regions (Coleoptera: Staphylinidae: Aleocharinae)
    download www.zobodat.at Linzer biol. Beitr. 49/1 341-368 28.7.2017 On some Athetini from Armenia and adjacent regions (Coleoptera: Staphylinidae: Aleocharinae) Volker ASSING & Jürgen VOGEL A b s t r a c t : Nine species of Athetini from Armenia are described and illustrated, eight of them for the first time: Atheta (Atheta) brevapicalis nov.sp. (South Armenia); A. (A.) hamulata nov.sp. (South Armenia); A. (Dimetrota) bispinosa nov.sp. (Armenia, Georgia); A. (D.) senticollis nov.sp. (North Armenia); A. (Oreostiba) altiviva BENICK, 1974 (widespread in Armenia); A. (O.) semialba nov.sp. (widespread in Armenia); A. (O.) abscisa nov.sp. (widespread in Armenia); A. (O.) brevitheca nov.sp. (widespread in Armenia); Liogluta armeniaca nov.sp. (Central and South Armenia). Three synonymies are proposed: Atheta hansseni STRAND, 1943 = A. brachati ASSING, 2013, nov.syn.; Liogluta granigera (KIESENWETTER, 1850) = L. trigemina (EPPELSHEIM, 1880), nov.syn.; L. funesta EPPELSHEIM, 1890 = L. nigrobusta ASSING, 2016, nov.syn. A lectotype is designated for Homalota trigemina EPPELSHEIM, 1880. K e y w o r d s : Coleoptera, Staphylinidae, Aleocharinae, Athetini, Liogluta, Atheta, Armenia, taxonomy, new species, descriptions, new synonymies, new subgeneric assignment, lectotype designation. Introduction According to SCHÜLKE & SMETANA (2015), only ten species of Athetini had been recorded from Armenia by the end of 2014, seven of Atheta THOMSON, 1858, one of Hydrosmecta THOMSON, 1858, one of Liogluta THOMSON, 1858, and one of Pycnota MULSANT & REY, 1873. A preliminary research of faunistic literature dealing with the Staphylinidae fauna of Armenia revealed that this list is not complete. Nevertheless, in view of the fact that the Athetini is a mega-diverse tribe represented in the Palaearctic region by about 2000 species or more in numerous genera, it can be concluded that more than a hundred species should be present in Armenia and that next to nothing is known about the Athetini fauna of this country at present.

How symbiotic lifestyles evolve from free-living ecologies is poorly understood. Novel traits mediating symbioses may stem from preadaptations: features of free- living ancestors that predispose taxa to engage in nascent interspecies relationships. In Metazoa’s largest family, Staphylinidae (rove beetles), the body plan within the subfamily Aleocharinae is preadaptive for symbioses with social insects. Short elytra expose a pliable abdomen that bears targetable glands for host manipulation or chemical defense. The exposed abdomen has also been convergently refashioned into ant- and termite-mimicking shapes in multiple symbiotic lineages. Here we show how this preadaptive anatomy evolved via novel Hox gene functions that remodeled the ancestral coleopteran groundplan.

  • Molecular Phylogeny of the Beetle Tribe Oxypodini (Coleoptera: Staphylinidae: Aleocharinae)
    Systematic Entomology (2013), 38, 507–522 DOI: 10.1111/syen.12011 Molecular phylogeny of the beetle tribe Oxypodini (Coleoptera: Staphylinidae: Aleocharinae) JUDITH OSSWALD, LUTZ BACHMANN and VLADIMIR I. GUSAROV Department of Research and Collections, National Centre for Biosystematics, Natural History Museum, University of Oslo, Oslo, Norway Abstract. This is the first study to comprehensively address the phylogeny of the tribe Oxypodini Thomson and its phylogenetic relationships to other tribes within the staphylinid subfamily Aleocharinae. Using the hitherto largest molecular dataset of Aleocharinae comprising of 4599 bp for representatives of 22 tribes, the Oxypodini are recovered as non-monophyletic. Members of the tribe belong to three distantly related lineages within the Aleocharinae: (i) the Amarochara group as sister clade to the tribe Aleocharini, (ii) the subtribe Tachyusina within a clade that also includes the tribes Athetini and Hygronomini, (iii) all other Oxypodini in a clade that also includes the tribes Placusini, Hoplandriini and Liparocephalini. Based on the inferred phylogeny, five subtribes of the Oxypodini are recognized: Dinardina Mulsant & Rey, Meoticina Seevers, Microglottina Fenyes, Oxypodina Thomson and Phloeoporina Thomson. The following changes in the classification of the Aleocharinae are proposed: (i) Amarochara Thomson is removed from the Oxypodini and placed in the tribe Aleocharini; (ii) the subtribe Taxicerina Lohse of the Athetini is reinstated as tribe Taxicerini to include Discerota Mulsant & Rey, Halobrecta Thomson (both removed from the Oxypodini) and Taxicera Mulsant & Rey; (iii) the subtribe Tachyusina Thomson is excluded from the Oxypodini and provisionally treated as tribe Tachyusini; (iv) the oxypodine subtribe name Blepharhymenina Klimaszewski & Peck is placed in synonymy with the subtribe name Dinardina Mulsant & Rey.

Holland Department of Entomology Purdue University 901 West State Street West Lafayette, Indiana 47907 ABSTRACT Two-hundred and nine taxa (171 identified to species level), in 111 genera, of staphylinid beetles were documented during a 21-year field survey of a national park site (George Washington Memorial Parkway) that spans parts of Fairfax and Arlington counties in Virginia. Fifty-two species, plus five additional genera, documented from the Parkway are first records for Virginia. An additional 62 species new to Virginia are listed in the appendix from broader research documenting 792 species of Staphylinidae from Virginia, Maryland, and the District of Columbia. The study also increases the number of staphylinid species known from the Potomac River Gorge to 167. Of the seven capture methods used in the survey, Malaise traps were the most successful. Periods of adult activity, based on dates of capture, are given for each species. Relative abundance is noted for each species based on the number of captures. Notes on morphological characteristics and habitats are given for some species. Thirteen species adventive to North America are documented from the Parkway and 60 adventive species are recorded from Virginia, Maryland, and the District of Columbia in the Appendix.
